As a key component for connecting infusion sets, syringes, and other equipment in the medical field, the performance of the Ruhr cone connector directly affects the safety and reliability of clinical use. The following are for beginnersRuhr cone joint performance testerOperation guide, covering the entire process from preparation to testing completion:

1、 Equipment preparation and calibration

1. environment check
   Place the tester on a stable and vibration free operating platform, avoiding direct sunlight or high temperature and humidity environments. Ensure that there are no strong electromagnetic interference sources around (such as large motors, welding machines) to avoid affecting data accuracy.

2. Power on and self check of equipment
   Connect the power adapter and turn on the host power, observe if the indicator light is on normally. Some models require starting a self-test program through touch screen or buttons to confirm that there are no abnormal alarms in modules such as sensors, pressure devices, and data acquisition systems.

3. Calibration operation
   According to the equipment manual, calibrate the force sensor using standard weights or specialized calibration tools. For example, if the testing separation force range is 20N-40N, a standard weight is needed to verify whether the sensor reading error is ≤± 0.2N. The pressure sensor needs to be calibrated by injecting gas or liquid at a known pressure to ensure an error of ≤± 5kPa.

2、 Sample installation and parameter setting

1. Sample cleaning and pretreatment
   Wipe the surface of the Ruhr connector with a dust-free cloth to remove impurities such as oil and dust. For joints that require sealing testing, it is necessary to ensure that the interior is dry and free of residual liquid.

2. Install sample
   Fix the joint onto the dedicated fixture of the tester, ensuring it is concentric with the fixture and not loose. If testing the leakage performance, it is necessary to connect standard steel joints (such as outer or inner cone joints) and use sealing gaskets to prevent leakage of the testing medium.

3. Parameter Settings
   Set parameters according to testing standards (such as ISO 80369, GB 1962):

• Leakage testSet the internal water pressure to 300kPa and maintain it for 30 seconds;

• Separation force testSet the axial force to 25N, loading rate to 10N/s, and holding time to 10 seconds;

• Unscrew torque testSet torque range 0-1.5N · m, rotation angle ≤ 90 °.

3、 Perform testing and data recording

1. Start testing
   Click the 'Start Test' button, and the device will automatically apply pressure or torque. During the testing process, it is necessary to closely observe the instrument display screen to confirm that the pressure/force curve is stable without sudden changes and there are no abnormal alarms.

2. Key operating points for key testing items

• Leakage testDuring the pressure holding period, observe whether there are water droplets leaking out from the joint connection. If there is continuous leakage, it is judged as unqualified.

• Separation force testRecord the maximum axial force value during joint separation. If it is lower than 25N, it does not meet the standard.

• airtightness testInject gas into the joint, maintain pressure for 5 minutes, and observe the pressure drop. If it exceeds the allowable range, it is judged as a leak.

3. Data saving and exporting
   After the test is completed, the device automatically generates a report containing the test curve, peak data, and judgment results. Export data to a computer via USB interface or LAN, and save it in Excel or PDF format for subsequent analysis.

4、 Maintenance and precautions after testing

1. Equipment cleaning
   Rinse the testing chamber and fixtures with clean water to prevent residual testing media from corroding the equipment. For hydraulic systems, it is necessary to drain the liquid from the booster pump and wipe it clean.

2. regular maintenance
   Inspect vulnerable parts such as sensors and seals every quarter, and replace aging components. Contact the manufacturer annually for comprehensive calibration to ensure long-term stability of the equipment.

3. Safety operation standards

• Wear goggles when testing high-voltage projects to prevent liquid splashing caused by joint rupture;

• Avoid direct contact with high-temperature components (such as heating modules) by hand;

• Non professionals are not allowed to disassemble the core modules of the equipment to avoid damaging the precision sensors.

Through the above steps, beginners can systematically master the operating points of the Ruhr cone joint performance tester, ensuring accurate and reliable test results and providing strong support for quality control of medical devices.
